NCV8152
Dual 150 mA, Low I
Q
, Low
Dropout Voltage Regulator
The NCV8152 is 150 mA, Dual Output Linear Voltage Regulator.
Device provides a very stable and accurate voltage with ultra low
noise and very high Power Supply Rejection Ratio (PSRR) suitable for
RF applications. The NCV8152 is suitable for powering RF blocks of
automotive infotainment systems and other power sensitive device.
Due to low power consumption the NCV8152 offers high efficiency
and low thermal dissipation.

Description
Regulated output voltage of the first channel. A small 0.22
mF
ceramic capacitor is needed from this pin to
ground to assure stability.
Regulated output voltage of the second channel. A small 0.22
mF
ceramic capacitor is needed from this pin
to ground to assure stability.
Power supply ground. Soldered to the copper plane allows for effective heat dissipation.
Driving EN2 over 0.9 V turns−on OUT2. Driving EN below 0.4 V turns−off the OUT2 and activates the active
discharge.
Input pin common for both channels. It is recommended to connect 0.22
mF
ceramic capacitor close to the
device pin.
Driving EN1 over 0.9 V turns−on OUT1. Driving EN below 0.4 V turns−off the OUT1 and activates the active
discharge.
Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation.
